Does it have a vin? There will be either an A or Y or 9 for the engine code of what originally came in the car. I believe 1986 used the ecm in the ac system like the 87-88 models did but not 100% sure. I do know 86 started out with 198 compressors and switched over to the 622 later in the model year but unsure of the control setups.

Yeah it has a vin, ill have to look at that tonight for whatever reason it never crossed my mind to check the vin for the engine code. One of my many moments! 1986 did use the ECM unfortunately and was one of the things that wasnt on my mind when i got the harness until i went to hooking everything up. I had thought about looking for an earlier harness just to help uncomplicate the situation.
